Great product

My son is loving this ring. He wears on his middle finger and is loving the fit. He feels like he is getting great information to help with his health journey.

This ring is great of you want to track your sleeping and quality of sleep, but lacks the accuracy for cardio and step tracking. I was sitting in my car driving for 14 hours straight and found after my drive I tracked over 16,000 steps!

The item was easy to pair and provided great information. For me, it was uncomfortable to wear and made it a bit difficult to do daily tasks. While I am more tempted to wear a ring more constantly than a watch, this is a bit uncomfortable.
